To make algorithm clear, I designed
pythonrun::array_list::ArrayListto always have minimum capacity to hold pointers.But I found a bug. In current implementation, when arraylist's length becomes 0 from 1, excess capacity remains and causes memory leak.
It's my mistake, sorry 😓
@konstin
This is a serious bug so could you please release 0.5.3 with this PR?
